CONTROLLING AND ALARM DEVICE.

Specification of Letters Patent.

PatentedNov; 21,1916.

Application filed June 5, 1915. Serial No. 32,338.

To all whom it may concern Be itknown that I, LOUIS M. PLANSOEN, a subject of the Queen of the Netherlands and a residentof Garfield, in the county of Bergen and State of New Jersey, have in vented a new and Improved Controlling and Alarm Device, of which the following is a full, clear, and exact description.

The invention relates to paper-making machines of the F'ourdrinier type, and its object is to provide a new and improvedcontrolling and alarm device located at the delivery end of the endless wire screen or apron and arranged to shift the delivery end of the screen back to normal position in case of a deflection and at the same time" sound an alarm for the attendant to manipulate the usual hand guide roll at the other end of the machine.

In order to accomplish the desired result, use is'made of means controlled by the, screen and connected with a guide roller over which passes the screen to move the guide roller and the screen bodily in a trans verse and longitudinal direction on a deflection of the screen.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the .controlling and alarm device as applied; Fig. 2 is an enlarged side elevation of the same; Fig. 3 is a plan view of the same; Fig. 4 is a transverse section of the same on the line l-d of Fig. 2; Fig. 5 is a sectional side elevation of a portion of the shifting means for the guide roller bearing; Fig. 6 is a transverse section of the toothed wheel and double pawl for actuating the toothed wheel; Fig. 7 is an enlarged face view of one of the guides for the circuit closing rods, the insulation being shown in sectionyFig. 8 is a diagrammatic view of the electric alarm; and Fig. 9 is a side elevation of a modified form of the electric alarm.

The endless wire screen or apron A of usual construction is mounted to travel in the direction of the arrow 6/ and at its delivery end passes around the usual roll B, and near the said delivery end it passes over a guide roller C. The shaft C of this guide roller C is journaled at each end in a bearh1g1) mounted to slide on a guideway E formed on a bracket E attached to the main frame F of the F ourdrinier machine and disposed obliquely relatively to the axis of the guide roller C, as plainly indicated in Fig. 3. In the bearing D is mounted to turn a nut G (see Fig. 5) screwing on a screw rod H attached at its ends on arms E forming part of the bracket E. On the nut G is secured or formed a bevel gear wheel G in mesh with a bevel gearwheel I attached to or formed integrally on the back of a wheel I having internal teeth P, as plainly illustrated in the drawings.

The teeth I of the wheel I are adapted to be engaged by either end of a double pawl J having a pivot J journaled in an arm K mounted to swing loosely on a stud K secured to the 'front of the bearing D and on which stud K turns loosely the wheel I (see Fig. 4). The arm K is pivotally connected by a link L with a crank pin L held on the end of the shaft C of the guide roller 0 so that when the latter is rotated the crank pin L and the link L impart a continuous rocking motion to the arm K. Now as longas the pawl J is in the normal inactive position shown in Fig. 2, that is, with both ends out of engagement with the teeth P, then the wheel I remains at a standstill, but when the pawl J is tilted in either direction the then uppermost end engages the teeth I to turn the wheel I in the corresponding direction. The rotary motion of the wheel I is trans mitted by the gear wheels I and G to the nut G screwing on the rod H and held in the bearing D so that the latter is shifted on the guideway E either to the left or to the right according to the direction in which the wheel I is turned at the time.

The tilting of the pawl J is controlled by the screen or apron A 011 the deflection thereof in alateral direction, and for this purpose the following arrangement is made: On the pivot J of the pawl J is secured a downwardly extending arm N in the lower end of which is mounted to turn an eye N through which extends loosely a rod 0 provided on opposite sides of the eye N with springs O, O abutting against collars 0 attached to the rod 0. The rod 0 is slightly inclined and its upper end is provided with a screw thread on which screw nuts 0, O engaging opposite sides of a bell crank lever P fulcrumed on the pivot P attached to the armE of the bracket E. The bell crank lever P is pivotally connected with a transversely extending bar Q passing are connected by circuit wires T, T with under the upper run of the apron or screen one pole of a battery T connected at its A immediately in front of the roller C. other pole by a circuit wire T with an alarm The bar Q, is mounted to slide transversely T of any approved construction and prefin suitable bearings on an arm E forming erably attached to the frame F. The return part of the bracket E and the said bar is Wire T of the battery T is connected with provided with lugs Q, (one only being the rod 0 and consequently electrical conshown) held adjustably on the bar by set nection is had by way of the several parts screws Q The lugs Q engage the side With the wheel I. Now when the bearing edges of the apron A so that when the latter D is moved from the right to the left, as is deflected in a transverse direction then previously explained, the wheel I moves movement is given to the bar Q in a like with it in the same direction and finally direction whereby the bell crank lever P engages the rod R thus closing the circuit is caused to swing and the rod 0 is caused for the alarm T to sound the alarm. In a to impart a swinging motion to the arm N like manner when the bearing D is moved so to rock the pawl J so that one end thereof from the left to the right, the wheel I moves engages the teeth I. As the arm K is coninto engagement with the rod R to close tinually rocked by the rotating shaft C of the circuit and to sound the alarm T The the guide roller C it is evident that when rods R and It are adjustably held in their the pawl J is in engagement with the teeth bearings S, S and for this purpose the outer I a turning movement in one direction is end B of each rod R, It is provided with given to the wheel I for shifting the beara screw thread on which screws a nut R ing D on the guideway E, as previously eX- abutting against the outermost bearing S plained. When this takes place the guide or S.

The rotary motion of the normal position the spring R returns the wheel I now causes the nut G to turn to corresponding rod It or R to its normal adshift the bearing D from the right to the justed position. By adjusting the nuts R left on the guideway E thus moving the on the ends R the rods can be set nearer to guide roller C in the direction of the arrow or farther from the peripheral face of the b, that is, in the direction in which the wheel I to make contacts sooner or later for apron A is deflected. In case the apron A closing the circuit whenever the wheel I is is deflected in the inverse direction of the shifted to the right or left as previously eX- arrow 1) then the pawl J is turned so that plained. The contact rods R, It may be its right-hand end engages the teeth I of arranged on opposite sides of the shaft C, as the wheel I to turn the latter in the inverse shown in Fig. 9, so that when the bearing direction of the arrow 0 thus causing the D, and with it the shaft C, is shifted either bearing D to travel from the left to the right to the right or left, then the circuit is closed 11 whereby the roller C is moved bodily in the and the alarm is sounded. inverse direction of the arrow Z). An auxiliary circuit closer is provided In order to notify the attendant of the which is directly manipulated by the screen Fourdrinier machine that the screen or or apron A and for this purpose use is made apron A has deflected,useis made of an alarm of a transverse bar U mounted to slide for the attendant to manipulate the usual transversely in. suitable hearings on arms E guide roll at the other end of the screen to arranged on the bracket F. The bar U is correct the deflection thereof at its starting provided with lugs U adjustably secured end. For the purpose the following arto the bar by set screws U and the said rangement is made: On opposite sides of the lugs U engage the edges of the apron A. wheel I are arranged contact rods R, R The ends of the bar U are provided with mounted to slide in guideways S, S of incontact lugs V, V connected with each sulating material and attached to the guideother by a circuit wire W also connected way E and the frame F, respectively, as with the circuit wire T of the alarm T". plainly shown in Fig. 2. The rods It, R The lugs V and V are adapted to engage springpressed rods V V similar to the rod R, R above described, and connected with each other by a circuit wire W which is also connected to the circuit wires T, T and consequently with the battery T It will be noticed that when the screen or apron A is deflected in the direction of the arrow 7) then the bar U is carried along and its contact lug V engages the spring-pressed rod V thus closing the circuit and sounding the alarm T In a like manner when the screen or apron A is clefiected in the inverse direction of the arrow 6 then the contact lug V engages the rod V to close the circuit for sounding the alarm T From the foregoing it will be seen that the device controls the guide roller C on any deflection of the screen or apron A and at the same time an alarm is given so that the attendant can quickly manipulate the usual hand guide roll at the starting end of the apron to return the latter to correct position. It is well known that in case the screen or apron A runs oil the end of the roll B it is wrinkled or doubled up or otherwise injured and hence its usefulness is practically destroyed. It is also well known that the attendant of a Fourdrinier machine is mostly occupied with the general supervision of the machine and cannot continually watch the correct or incorrect running of the screen or apron A, but when the alarm T is sounded as above described then the attendant can quickly manipulate the hand guide roll to readjust the screen or apron A.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
